I'm happy to announce that I will give a free 4h workshop on code deobfuscation at #r2con2021 (probably at September 30, 5:00 PM CEST). This time we will break VM-based obfuscation with symbolic execution. Stay tuned!

So many talks to choose from at our event on 7/11! Why not consider "Automating Binary Deobfuscation Processes: Dynamic Taint Analysis and Symbolic Code Execution" presented by Usama Saqib and Berk Cem Goksel?
